Jezequiel Family Book

The Jezequiel Family Book is a reference volume documenting all the monsters the Jezequiel family has encountered through the ages while protecting the demonic portal under their guard. The book contains information on the strengths and weaknesses of each monster, along with drawings and any background information the family acquired in their encounters. A second book is hidden within the main volume which, when deciphered, details how to open the demonic portal to Lord Trash's realm.

After Robert's encounter with Renata and Brant, Renata entrusts the book to Robert in order to aid in his fight against the Tenebrae.
